Though both sides still have thirteen league games left to play, today's match up at The Emirates feels like a decisive fixture for Arsenal and Leicester .

Having flown in the face of all expectations this season, Claudio Ranieri's Foxes are currently five points ahead of The Gunners at the top of the table. If they win this match, their lead over Arsenal will look practically insurmountable.

Likewise, Arsene Wenger's men can haul Leicester in with a victory of their own. They'll need to be at their very best if they're to overcome the league leaders.

As such, it's far from ideal that Wenger's been forced into a change ahead of the crunch clash. With Gabriel Paulista out with a hamstring tweak, Per Mertesacker is set to start.

That's right. Mertesacker, with all the mobility of a 1950s fridge, is set to face the blistering pace of Jamie Vardy and Riyad Mahrez . So, how have Arsenal fans reacted to the news?

Well, we think it's fair to say that most of them are absolutely terrified.

Some are seriously worried about Mertesacker right now...

Others think Vardy and co. are going to have a field day...

While some Arsenal fans are losing their minds over the whole thing.

Let's hope for their sake that Mertesacker gets a bit of help from his teammates today. He certainly isn't going to contain Leicester's attack alone.
